SAND-PIPE FOR LOCOMOTIVES.

SPECIFICATION forming part Of Letters Patent No. 435,210, dated August 26, 1890. Application filed June 26, 1890. Serial No. 356,874. (Nomodel.)

To (1% whom it may concern:

Be it known that I, MIoHAEL DALY, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and usefulImprovements inSand-Pipes for Locomotives, &c.; andI do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and usethe same, reference being had to the accompanying drawings, which form apartof this specification.

My invention relates to a sand-pipe nozzle for locomotives; and itconsists of a double tube, or one pipe within the other, as will befully set forth hereinafter.

In the accompanying drawings, Figure 1 is a sectional elevation of myimproved nozzle, which is constructed in accordance with my invention.Fig. 2 is an enlarged inverted plan view of the nozzle. Fig. 3 is asectional elevation of the lower portion of the nozzle.

To construct a sand-pipe nozzle in accordance with my invention, Iprovide a short section of pipe at and bevel the lower portion 7)inwardly, and form a flange or bead c on the upper end of the same. Inow provide anothersection of pipe (1, of less diameter and somewhatshorter, having on its lower end a flange e for centering the samewithin the larger tube a, and another flange f at its upper end for thesame purpose. These concentric tubes CL (1, when in posit-ion, areattached by a coupling g to the sand-pipe h of a locomotive. Theenlarged flange e at the lower end of the inner pipe dis provided with aseries of notches e in its edge, and as the flange fits snugly withinthe outer pipe athe notches provide openings e for the circula tion ofair in the spaces between the concentric pipes. By means of a nozzlesuch as described the sand is prevented from becoming moist and adheringto the same. The beveled portion will prevent water from entering oradhering to inner walls of the tube a, and the sand passing down theinner pipe (l will be free from moisture, as a current of air ispermitted to freely circulate about the -space between the two pipes to(1.

Having thus described my invention, I claim 1. The herein-describedsand-pipe for locomotives, consisting of a double pipe, the one withinthe other, the said inner pipe being shorter than the outer casing, asuitable union having a cup-shaped flange fitted therein and joined tothe upper extremity of the inner pipe for the purpose of supporting thesame, and an annular bead provided with suitable vents, secured to thelower extremity of the said inner pipe, whereby a current of air mayenter the said vents and freely about the inner pipe to preventmoisture, and the said bead serving to center the lower end of the saidpipe, substantially as set forth and described.

2. A sand-pipe for locomotives, consisting of the outer tube a, and aninner tube arranged concentrioally within said outer tube to leave anintermediate air-space, and provided with the centering-flange havingthe airopenings, for the purpose described, substantially as set forth.

In testimony that I claim the foregoing I hereunto atlix my signaturethis 9th day of April, A. D. 1890.

MIcI-IAEL DALY, [n s] J. A. HERRON.
